COMPOSITE ANTI-RESTENOSIS DRUG FOR CORONARY DRUG-ELUTING STENT AND CONTROLLED RELEASE SYSTEM THEREOF
Publication number: 20200384161Abstract: A composite anti-restenosis drug for use with a coronary drug-eluting stent, and a controlled release system for the drug. The composite drug comprises arsenic trioxide and rapamycin, which may be used in combination to prevent in-stent restenosis and reduce the incidence of intravascular thrombosis. The controlled release system for the composite drug may control the release of the composite drug so as to achieve the therapeutic effect of controlling restenosis and preventing the formation of thromboses.Type: ApplicationFiled: July 20, 2018Publication date: December 10, 2020Applicant: XINXIN MEDICAL TECHNOLOGY (SHANGHAI) CO.

Patent number: 6579007Abstract: An intraoral x-ray film packet is taught which includes a molded thermoplastic frame (preferably injection molded) to which an x-ray dental packet is sealed. The sealing method can be any one of a number of processes including, but not limited to RF sealing, induction heat sealing, or ultrasonic sealing, as well as using any one of various adhesives to affix the x-ray dental packet to the frame. The injection molded thermoplastic frame provides a cushion to buffer and a soft rounded edge to mask the sharp edges that occur on plastic encased x-ray dental packets. Sealing of the injection molded thermoplastic frame to the x-ray dental packet during manufacture results in a packet which includes a comfort enhancing perimeter frame permanently integrated therewith. In such manner, the dental film packet is manufactured with an integrally formed perimetric cushion. The dental film packet is preferably formed with an outer envelope wherein one of the opposing outer sheets is more rigid than the other.Type: GrantFiled: March 24, 2000Date of Patent: June 17, 2003Assignee: Eastman Kodak CompanyInventors: Richard W.

Patent number: 6575089Abstract: A method and apparatus for embossing plastic web materials, for instance, low density polyethylene film, have a movable, first embossing element having a plurality of male dies associated with a heat transferable member and a stationary, second embossing element having a plurality of female dies. The temperature of the heat transferable member is controllable so that the male dies can deform a range of deformable plastic materials. The stationary, second embossing element is alignable relative to the first embossing element and unheated so that the female dies are maintained at about ambient temperature during embossing.Type: GrantFiled: March 3, 2000Date of Patent: June 10, 2003Assignee: Eastman Kodak CompanyInventors: Fugui He, Harold Moore, Douglas G.

Patent number: 6502471Abstract: A method and apparatus for evaluating the end cap round transducer horn assemblies used in debubbling operations wherein the ECR THA can be evaluated off-line at both high and low power and on-line by making electrical measurements on the ECR THA. The electrical measurements are used to characterize the physical condition of the piezoelectric ceramics of the THA. A test box is employed to practice the method. The test box is connected between the THA and a signal analyzer. Power is supplied to the THA and the electrical signals across the THA are sampled. The sampled electrical signals are transmitted to the signal analyzer while maintaining the amplitude and phase relationship thereof. The sampled electrical signals are used to generate an impedance trace for the particular THA. That impedance trace is compared to a model impedance trace. In such manner, it can be determined whether the ECR THA is operational.Type: GrantFiled: January 5, 2000Date of Patent: January 7, 2003Assignee: Eastman Kodak CompanyInventors: Robert Peter Kraus, Jr., Fugui He, Roland J. Koestner, Steven D. Possanza, Paul P. Zontek
